Abstract: A tool for pressing a multilayer press packet, particularly for placing inside a press, preferably for inserting into the insertion opening of a multiplaten press. The multilayer press packet, in particular, has a number of multilayers that are separated from one another by at least one separating plate. The tool can be electrically heated. The tool forms a cohesive unit with a heating element arranged between two heat transfer plates and/or between a heat transfer plate and a cover plate. The tools have at least one electric connecting terminal corresponding to contact terminals on the press.

Abstract: A pressing and heating system for pressing of a multilayer press assembly in which the multilayer press assembly may have a plurality of multilayer sets of material, for fabrication of printed circuit boards or the like, which are mutually separated by at least one separating plate. The system contains at least one tool that is to be inserted in an insertion opening of a stacked press. The tool being of a form that is electrically heatable, for the purpose of which heating at least one electrically powered heating element is provided, and the system further contains a control unit for controlling the heating element. With the aim of improving such a system, at least one thermocouple element is provided.

Abstract: The invention relates to a partition (1) or a method for producing a partition (1) for a multilayer pressed packet (3), wherein the partition (1) can be placed as a pressing sheet in the composite of a multilayer pressed packet (3) to be produced, especially between two multilayers (2). The unfavorable image transfer between the multilayers (2) that has occurred in the prior art up to now is cost-effectively prevented in that the partition (1) is implemented as a steel sheet, but not as a high-grade steel sheet, and that the steel sheet—at a temperature of essentially 180?C—possesses a tensile strength of at least Rm ? 500 Mpa and/or—at a temperature of essentially 180?C—a yield strength of at least Rp0.2 ? 470 MPa.

Abstract: A separating plate compound component (1) for producing printed circuit boards by compressing multilayers (2) stacked with at least one such compound component (1), which compound component (1) includes a separating plate (3) between copper foils (5), anti-adhesive layers (6) being arranged on the separating plate (3) between the latter and the copper foils (5).

Abstract: This technique involves joining copper foils of any type and thickness to aluminum sheets of any alloy and thickness in order to simplify the assembly of multilayer press books, whereby two copper foils of any type and thickness and one aluminum sheet of any alloy and thickness are joined in such a way that the joint is located outside the surface of the aluminum separator. At the same time, the registration slots required for the multilayer press can be punched. The selected copper foil panels.are slightly larger than the aluminum sheet. When the aluminum separators thus covered with a copper foil on both sides are subsequently placed into the press together with the epoxy resin fabrics (prepregs) for laminating the multi-layer, the aluminum sheet can expand unhindered during heating without causing any surface tension on the copper foils.

Abstract: A hardened aluminum alloy, for use in the manufacture of printed circuit boards, having elevated levels of manganese and magnesium and produced as a sheet by a cold rolling process to a specified thickness.
